- Abstract
as an important sign of deterioration of soil environmental health quality, soil heavy metal pollution is closely watched by scholars at home and abroad. Combined the Kriging Interpolation method in the GIS spatial analysis, this paper evaluated the Cu, Zn, Pb, and Cr heavy metal spatial pollution status around the Qinghai Lake region using the methods of single-factor pollution index and the Nemerow compresensive pollution indices. Results showed that surface layer soil around the Qinghai Lake region was slightly polluted by Cu, Zn, Pb and Cr, while Cu pollution mainly occurred in Daotanghe Town and Jiangxigou Countryside in the southern bank of the Qinghai Lake, Quanji Countryside and Haergai Countryside in the northern bank of the Qinghai Lake; Zn, Pb and Cr pollutions have similar spatial traits, which chiefly occurred along Daotanghe-Jiangxigou countryside, the other regions showed no pollution by these elements. Nemerow Pollution Index showed that soil pollution around the Qinghai Lake region were slightly polluted by four heavy metals, which reminds us that we should pay sufficient attention to tourism and densely populated area around this region.
